KPX340-C 12.0 mm Dia. x 20 mm FL; MgF2 Coated; Plano-Convex Lens MgF2 400-700nm

The KPX340-C is a Plano-Convex lens, a type of spherical lens, sourced from MKS/Newport. This lens, with a circular base shape, is designed for use in the visible light spectrum, specifically optimized for the wavelength of 589 nm. The lens is made of n-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost.

The lens has a diameter of 12.0 mm and a thickness at the edge of 2.0 mm. The center thickness is 3.9 mm, and the effective focal length (EFL) is 20 mm. The radius of curvature for the first surface (R1) is 10.374 mm, and the back focal length (BFL) is 17.4 mm. The inner radius is 0 mm, indicating a meniscus lens.

The KPX340-C is coated with MgF2 on both the front and back surfaces. This coating, known for its excellent optical properties, reduces reflection and increases transmission in the spectral range of 400-700 nm. The lens is currently in stock and available for immediate purchase. For more information, please refer to the vendor's website.
